The greenhouse effect is the way the greenhouse gases (water vapour, carbon dioxide, methane etc) in the atmosphere trap the sun's heat to keep the planet warm. This effect is supported by the water and carbon cycles of the earth, and has been going on since life began.Global Warming is the warming of the earth during the past 200 years but especially since about 1970. Man discovered and started burning fossil fuels (coal, oil and natural gas) which releases carbon dioxide into the atmosphere that had been hidden away for millions of years. This extra CO2 is disrupting the natural greenhouse effect and is causing the enhanced greenhouse effect.It is this enhanced, or accelerated, greenhouse effect that is responsible for global warming.A:Global warming, as the word has been used in recent
